BESSEMER, Alabama- A 13-year-old girl was held against her will, and then raped and sodomized over three days by at least five men – three adults and two juveniles.

The Bessemer Police Department is conducting the human trafficking investigation, Lt. Darron Hunter confirmed to AL.com. Three adult men and two juveniles have been charged already, and other charges are expected next week.

Hunter said investigators can't release too many specifics about the case because of its sensitive nature, and the ongoing investigation. The girl, he said, didn't know any of the men involved. How she came to be with the men remains part of the continuing investigation.

The girl was held against her will from July 26 through July 28, Hunter said, and passed around among the men at various locations. She was living in Bessemer at the time of the assault.

Asked if there was a missing persons' report filed on the girl during that three-day period, Hunter said that too is under investigation.

The girl was eventually able to escape and flee her attackers. The agencies involved in the investigation are Bessemer police, the Jefferson County District Attorney's Office in the Bessemer Cutoff, the Department of Human Resources and the Alabama Department of Forensic Sciences.

So far, authorities have charged the three adult men and the two juveniles. The juveniles' names are not being released because of their ages. They could end up being charged as adults, Hunter said.

The adults charged are Derion Jeff Shumpert, Khalil Lamontray Bradley and Sammy Cooper Jr. All three are 19, and have ties to Bessemer. Cooper is charged with first-degree sodomy and remains in the Jefferson County Jail with bond set at $500,000, jail records show.

Shumpert is charged with second-degree rape. He was arrested July 28 and released from the Jefferson County Jail the following day on $25,000 bond, court records show.

Bradley is charged with second-degree sodomy.

Hunter said the victim is currently undergoing counseling.
